“No, extra fee for children not mentioned in her listing “
Guest is not necessary to pay the extra cleaning fee if the host didn’t mention in the listing announcements.
@Branka-and-Silvia0 was right in point of view.
It’s happen to me few times, guest arrival with children’s didn’t inform me in advance, guest explained was her fault by not correctly enter the numbers of person in the booking. I accepted and educated the guest is very important to do that in Airbnb platform or either commercial hotel.
I was pleased as they left the place clean without issues.
You may can try again to well communicate with host, as you are not intentionally and unaware of it’s. Hope she can change you in your budget fee and you will learn the lesson and beware for the future booking.
I hope you can resolve its.
